    • Oil intensified common rail injectors that combine a common-rail non-intensified injector with an oil-intensified injector. The invention also uses fuel (common rail) pumps that are commercially available since the injector does not rely on this pump for intensification function. Also, since the pressure of the fuel pump is limited to lower than the intensified pressure, the injected pressure is limited to the unit injector; this eases the rail and tube requirements to this lower fuel rail pressure. The injector operates up to this limited pressure with no intensification. Also a separate oil system is configured to operate a hydraulic intensifier. Thus the system is able to achieve very high injection pressure without common rail pump, rail, fitting and jumper tube limits. The oil system does not need to operate or run unless these elevated pressures are required. Embodiments using direct needle control are disclosed.
    • 将共轨非强化喷油器与增油喷油器相结合的加油共轨喷油器。 本发明还使用可商购的燃料(共轨)泵,因为喷射器不依赖于该泵用于增强功能。 此外,由于燃料泵的压力被限制为低于强化压力,所以注入的压力限于单元喷射器; 这使得轨道和管道要求降低到这种较低的燃油轨压力。 喷射器在没有强化的情况下运行到这种有限的压力。 另外,单独的油系统构造成操作液压增压器。 因此,该系统能够实现非常高的喷射压力,而不需要共轨泵,轨道,配件和跳线管限制。 油系统不需要运行或运行,除非需要这些升高的压力。 公开了使用直接针控制的实施例。
